The Philadelphia Marathon has grown tremendously since our first race in 1994. What started as a small local event of just 1,500 participants has become one of the top-10 marathons in the country. Our beautiful and scenic course takes runners past historic landmarks, through urban neighborhoods, and along Philadelphia's picturesque waterfronts. Of course, you can't forget the crowds.

Each year, spectators line the course, eager to cheer on runners, because there's nothing we love more in this town than champions.

Race Weekend 2021 features the AACR Philadelphia Marathon on Sunday, November 21; the Dietz & Watson Philadelphia Half Marathon, Rothman Orthopaedics 8K and Dunkin' Munchkin Run on Saturday, November 20; and a free two-day Health & Fitness Expo on Friday, November 19 and Saturday, November 20.

History of the Philadelphia Marathon

The beginnings of organized marathoning in Philadelphia date back to at least the 1920s when the race occurred on a course from the Philadelphia suburbs into the city. Mainly a suburban event, efforts were largely independent and promoted under various names over the years.

It was not until 1994 that the marathon became a City of Philadelphia-managed race held strictly within city limits. It was then that the Philadelphia Marathon Weekend as we know it today was officially established by the City and a group of dedicated runners-physicians at the Rothman Institute. The new city-centered course provided a perfect setting for the many historic and beautiful assets of Philadelphia.

The Philadelphia Marathon started out modestly with a mere 1,500 participants in 1994 and has grown to become one of the top-10 marathons in the nation. Today, the race is flourishing, with nearly 15,000 participants (note: 50% capacity due to COVID policy, as of May 12, 2021) expected to take part in all three races: The Rothman Orthopaedics 8K, as well as the AACR Philadelphia Marathon and Dietz & Watson Philadelphia Half Marathon.

The marathon remains true to one of its founding goals of promoting health and fitness, adding the health & fitness expo and a noncompetitive Dunkin' Munchkin Run to the experience.

Over the decades, the Marathon has experienced many enhancements, but one thing remains the same: The Philadelphia Marathon Weekend is famous for going the distance.
